Gave it a try today
Slick but also a reminder why I avoid Ubuntu. Problems with the latest/greatest? Well... Wouldn't ssh or https to anything while connected to the office via Openconnect. Odd really, because I was able to ssh from the corporate Dell to my shiny new Ubuntu VM. A colleague with deep knowledge of ssh helped me with the former. I'm still looking at the latter. I never have these problems with Mint and CENTOS. I've also spun up a Mint VM under Hyper-V, but that takes a little more effort (had to tell it what screen resolution to use, and copy/paste won't work between it and Windows, unlike a VirtualBox resident).
Also, Hyper-V isn't necessarily better than VirtualBox. Whereas Virtualbox sees your monitor as its monitor, connection to a Hyper-V is via Remote Desktop/X (the only way is headless, it seems). Overall performance is better, but graphic performance is a little sluggish. Good to muck around with these things.
